Lead - Alpha 0.001 - A First-Person Shooter

This is my first attempt at an FPS game that I have made using Unity. The game is called "Lead", and the player, so far, can destroy crates and barrels. It's pretty basic for now, but the first map, FortHome, is almost complete, as all it needs is a bit of texturing, which shouldn't take more than a few days. Anyway, here's the first Alpha version of the game. If you shoot all the barrels and crates, it'll probably entertain you for a minute or two.

Any feedback is welcomed warmly.

For Alpha 0.002, look forward to:

+Enemies

+Textured maps

+A new map

The game works on Windows, I'm unsure about other Operating Systems.
